Abstract
The invention discloses an adaptive pressure balanced air pressure wave signaling structure. The structure consists of upper and lower sealed workrooms, and a work plunger (1) with an oblique chamfer can block or communicate the two workrooms; during communicating, the high-pressure gas of the lower workroom (8) enters the upper workroom (9) to realize pressure balance; and the work plunger (1) enters a compressed gas preparation state during blocking, and the gas in the lower workroom (8) is compressed and discharged into a work cavity (11) through a connecting hole (7) during signaling so as to complete the signaling function.
Description
Technical field the present invention relates to be operated in a kind of structure that keeps the normal sender function of gas bullet barometric wave under (outside) hyperbaric environment.
The background technology oil is stored in the stratum, because the complexity on stratum, oil is different in the different phase of exploitation to every mouthful of oil well liquid-supplying amount.
In order to grasp the liquid supply rate of oil reservoir to every mouthful of oil well, just need the interior producing fluid level of monitoring oil well in real time, and use spring to promote the gas of plunger compression air chamber, produce the high pressure barometric wave as the signal source, by reflection interval of measuring echo and then the position of obtaining producing fluid level, be a kind of technology of often using at present.But this technology usually is subjected to the influence of gas pressure in the tested sleeve pipe, can't operate as normal.This be because, the gas pressure that plunger produces that promoted by the spring situation less than the interior gas pressure of (outside) sleeve pipe has appearred, this situation all can take place on most of oil wells.This has just limited the scope of application of this technology.
Summary of the invention is at the present existing in actual use problem of this technology, and the present invention has used a kind of self-adaptive pressure balanced type barometric wave sender structure.Principal character of the present invention is that the service depot that the signal source is transformed into by upper and lower two sealings is formed, can be with two service depot's blocking-up or conducting with the work plunger (1) of oblique chamfering; The conducting gases at high pressure of service depot (8) at present enters service depot (9), realizes pressure balance; Work plunger (1) just enters the Compressed Gas SBR during blocking-up, will descend the gas compression in the service depot (8) during sender and enters in the working chamber (11) by connecting hole (7), finishes the sender function.To achieve these goals, the impulse stroke of work plunger (1) has been done improvement, work plunger (1) is except the impulse stroke Y of normal Compressed Gas, and other has increased the current journey L of an additional guide.Work plunger (1) is designed to the structure with oblique chamfering, is to break away from joint ring (2) or enter when contacting in order to ensure work plunger (1) to protect joint ring (2) not to be damaged.
Need explanation any be: how the pressure in the pipe-in-pipe does not change, and structure of the present invention makes the pressure in the service depot of upper and lower two sealings be consistent all the time, that is to say that structure of the present invention has the effect of self adaptation casing pressure.
The present invention will be further described below in conjunction with Figure of description and embodiment.
Fundamental diagram when appended drawings 1 is basic structure of the present invention and upper and lower two service depot conductings.Accompanying drawing 2 is that upper and lower two service depots are when being blocked and enter the fundamental diagram of preparatory stage before the sender.Accompanying drawing 3 is the leading screw schematic diagrames that reset.
Specific embodiment accompanying drawing 1 has shown concrete structure schematic diagram of the present invention.Primary structure of the present invention reaches last service depot (9) by the work plunger (1) with oblique chamfering and following service depot (8) forms.Wherein, following service depot (8) links to each other with high-pressure working chamber (11) by connecting hole (7), and high-pressure working chamber (11) directly links to each other with sleeve pipe.
Formed the gap because of the current journey L of additional guide between the work plunger (1) of the oblique chamfering of band of the present invention and the joint ring (2), make service depot (9) and following service depot (8) under the state shown in the accompanying drawing 1 for communicating, the interior pressure of the gas pressure of two service depots and oil well casing is the same.
Other supplementary structure is:
The middle part of work plunger (1) is connected with leading screw (4) by nut (10), so just can make work plunger (1) upper and lower mobile by rotating threaded shaft (4).
The projection (5) on work plunger (1) top cooperatively interacts with the movable trigger (3) that is installed on the gas body (6), and the plunger (1) of can will working under big spring (12) compressive state is fixed on the top of gas body (6).
The top of gas body (6) is equipped with reductor (13) and motor (14), the output shaft of reductor (13) and rotating threaded shaft (4) are connected, the rotary power that provides by motor (14) by reductor (13) increase square after, rotating threaded shaft (4) is produced rotatablely move, it is upper and lower mobile to drive work plunger (1).
In order to guarantee certain gas discharge rate, it is enough big that the sectional area of work plunger (1) must design, because the restriction of power, the thrust of big spring (12) can not be infinitely great, therefore, corresponding to the sectional area of work plunger (1), the pressure reduction that compresses the sender gas in service depot (8) at present generally is no more than 1.5Mpa.So when gas pressure in the sleeve pipe surpassed 1.2Mpa, whole signal transmitter just was difficult to operate as normal.
The high-pressure working chamber that links to each other with sleeve pipe (11) has been owing to introduced gases at high pressure in the sleeve pipe, and gases at high pressure introduced time service depot (8) by connecting hole (7).Service depot (8) inner high voltage gas produces a thrust that makes progress to work plunger (1), this power is at the control lower compression big spring (12) of leading screw (4), after work plunger (1) walks to be over the current journey L of additional guide, the oblique chamfering disengaging of work plunger (1) bottom and contacting of joint ring (2), tiltedly the ring-like gap between chamfering and the joint ring (2) will descend service depot (8) inner high voltage gas to introduce last service depot (9), the back side at work plunger (1) has formed back pressure, with the thrust-balancing that made progress originally, make big spring (12) recover original thrust.
After structure of the present invention has been finished the pressure balance operating mode, just entered the preceding operating mode of preparing of sender, this operating mode has three phases.Be that the service depot is blocked stage, leading screw reseting stage and sender stage.
The service depot is blocked the stage: accompanying drawing 2 is that upper and lower two service depots are when being blocked, schematic diagram when additional guide is passed through journey L=0, this stage leading screw (4) counter-rotating, work plunger (1) is under the effect of big spring (12), move down a segment distance L, but the movable trigger (3) that is installed on the gas body (6) because of the projection (5) on work plunger (1) top stops that work plunger (1) is forced to rest on the top of gas body (6).
The leading screw reseting stage: accompanying drawing 3 is reset schematic diagrames when finishing of leading screw, and this stage leading screw (4) continues counter-rotating makes nut (10) break away from work plunger (1), reserves work plunger (1) the compression impulse stroke during the interior gas in service depot (8) down.
The sender stage: this stage leading screw (4) continues counter-rotating and shake-up activity trigger (3), and big spring (12) plunger (1) that pushes the work forward moves down rapidly, and generation high pressure gas corrugating becomes the signal source service depot (8) in.Since the gas pressure of two service depots be with oil well casing in pressure be the same, so structure of the present invention can guarantee that the high pressure gas corrugating becomes the signal source to exceed about about 1.2Mpa than the pressure in the sleeve pipe.
